Hello everyone,
I benefited a lot from other posters in this forum, so thought I'd give back by sharing my personal experience. Earlier today I charged to 100% for the first time in months just in order to see what the actual range is rather than one extrapolated from lower states of charge. Yes, I know that even with this approach the reading can be off, but I surmise that if the reading is 328.14 or 328.48, the precise range likely rounds to 328.
Here's the historical chart from TeslaFi showing calculated range from December last year, 3 months after I took delivery of my Model 3 LR. Interestingly, the battery shows no incremental degradation throughout the entire period that we have data for.
Over the 9 months and 10k miles, about half of the charging was from 50 kW DCFC stations. About 10% was supercharging, and 40% was Level 2 charging. I typically charged to around 70%-90% then ran the battery down. A few times I did charge to over 90% immediately before a lot of driving. Whenever I left the car at rest for a few days or longer, I made sure it had around 60% battery or less. So even though I charged to high SoC's often, the car didn't spend much time at over 60% SoC. Also, it's been a long and cold winter in LA, so storage temperatures have been very favorable.
Because I have a long work commute, and because I don't use home charging, I think I have relatively deep charge-discharge cycles, probably around 50%. I'm sure after a lot more miles this will catch up to me, but for now it's quite clear that calendar aging plays a much larger role.
Happy to answer any questions about charging habits. Otherwise, I think I'm an example of how keeping a Tesla at a low SoC is very effective in minimizing battery degradation.
